Very nice. But I might have liked it more if you had included someone a bit more plain. Like a lightly armed woodsman or farmer dressed in a simple tunic and trousers. But that depends on what you are trying to do.

Such a great image. The friendship between the various Northern factions has always fascinated me, and you've really managed to convey how they have come together at this moment; I can almost hear them singing as they march. This is just really excellently done.

I only noticed the scabbards in the end. Well, some early medieval/migration era swords were also worn on the right side, even by right handed swordsmen. (it seems unlikely, but it's entirely possible to draw a sword like that: [link] )

Touché! I though it would be too clumsy to draw a sword that way, using right hand, but well, I was wrong. The point is quite clear when one has a shield, or is mounted.

I usually draw scabbards here and there as I'm not aware of historical facts. Being left-handed myself I dont mind "inaccurate" drawings in that way. If it looks good, go for it!

One option in this kind of situations could be mirroring the picture, but for some reason people going to left refers to "going back" rather than "advancing" when going to right. I don't know what causes that "psychical" effect.
